Trial run!
Check the grinding belt before use. The grinding
belt must be installed properly and run without
hindrance. Do a test run for at least thirty seconds without
load. Do not use damaged, eccentric, or vibrating grind-
ing belts.

The optimal grinding results are obtained when the grind-
ing belt is steadily moved back and forth under slight
pressure.
The control electronics keep the belt speed virtually con-
stant during idle and load conditions for assured, consist-
ent work results.
Too great a pressure reduces machine efficiency and the
grinding belt's useful life.
The machine is equipped with an electronic control and
integrated overload protection.
If the machine is overloaded the belt blocks briefly. Im-
mediately remove all loads on the machine and keep it
running in the unloaded state for a short time.
Select a suitable belt speed.
When the contact pressure is too low the belt may
slip on the drive roller!

To work effectively and surely keep the
machine and the ventilation slots clean at
all times.
After approx. 150 operating hours check carbon brushes
and replace if necessary. Clean motor housing and re-
plenish grease filling in gearbox housing.
To maintain the protective insulation the machine must be
subjected to a technical safety inspection. This work must
be done exclusively by a specialized electrical workshop.
When working on metal under extreme working conditions
conductive dust deposits can occur inside the machine,
thereby impairing the protective insulation of the tool. In
such cases the use of a stationary vacuuming system,
frequent blowing out of the ventilation slots and protection
by a fault current protection switch are advised.

hAnging the cArBon Brushes
The Automatic-Stop feature protects the machine
from defects due to excessively consumed car-
bon brushes (230V).
The machine is equipped with two carbon brushes, i.e.
one is installed in each handle half. The carbon brushes
must be changed as follows:

aIntenance
Unscrew four screws and remove the handle halves.
Lift spring with screwdriver and remove brush. Install new
brushes. Clean carbon brush holders, making absolutely
sure not to change the carbon brush arrangement of the
carbon brush assembly. Fit handle halves and fasten with
four screws.
Repeat this change on the opposite side, making
absolutely sure to avoid both handle halves from
being opened at the same time.

repaired by an authorized SUHNER agency.
Any replacement needed for the connecting line must be
installed by the manufacturer or its agent if safety risks are
to be eliminated.
